The Cisco® Media Convergence Server 7825-H2 (MCS 7825-H2) is a powerful platform for Cisco Unified Communications applications and others. It occupies only 1 rack unit (1RU) while providing the features most requested in a server platform at a very economical price point:
• Intel dual-core, Pentium D, 2.8-GHz or 3.4-GHz processor with an 800-MHz front side bus (FSB) and 4 MB of Layer 2 cache
• 2 GB of installed PC2-4200 memory, error correction code (ECC), Double Data Rate 2 (DDR2), synchronous dynamic RAM (SDRAM) standard; 8 GB maximum
• Cisco Unified IP Interactive Voice Response (IP IVR)
• Cisco IP Interoperability and Collaboration System (IPICS) Software
• Cisco Unified MeetingPlace® Express
• Cisco Unified IP Queue Manager
• Cisco Unity® Unified Messaging
• Cisco Digital Media System
Primary Features and Benefits
The Cisco MCS 7825-H2 is a robust, highly available server platform designed to support today's IP Communications applications. It uses a single Intel dual-core Pentium D, 2.8-GHz or 3.4-GHz processor with an 800-MHz FSB.
The Cisco MCS 7825-H2 provides system-health LEDs and unit-identification lights on the front and back of the server to make locating system problems easier than ever. When an internal component fails, this indication is made on an internal-component LED (amber) and on the front panel of the Cisco MCS 7825-H2. If the item can be serviced if the hood is removed, as in the case of a fan failure, the internal-health LED illuminates. If no failures have occurred, the system-health LED is green. If the failure is critical and has caused the system to shut down, the LED is red.
In the Cisco MCS 7825-H2, the ROM is divided into two logical parts. When the system boots, the primary ROM side is executed and used in server operation. During a ROM flash, the backup side is flashed. When the flash is fully completed, the backup side becomes the primary. If under rare conditions the flash does not complete safely, potentially because of a power interruption, the backup is available to boot the system. If both images are valid, the user can select which image to use at boot time.
Serviceable SATA Disk Drives
The Cisco MCS 7825-H2 is configured with two 80-GB SATA "cold-pluggable" disk drives configured in a RAID 1 mirror set. The server continues to operate if either of the two disk drives fails. The SATA disk drives are accessible to the end user through openings in the front bezel of the server. If a drive fails, the end user can schedule server downtime, power down the server, and replace the failed SATA drive by simply removing it (each drive is equipped with a front latch that positively mates the drive to the server) and replacing it with an unconfigured spare drive. After restarting the server, the RAID 1 firmware initiates a remirroring of the new drive to help ensure that drive redundancy on the Cisco MCS 7825-H2 is maintained. The serial-drive technology introduced in the Cisco MCS 7825-H2 provides Cisco Systems® customers with a highly reliable, high-performance, cost-effective solution.
DAT Tape Drive Support
The Cisco MCS 7825-H2 can support an optional 36/72-GB USB external Digital Audio Tape (DAT) drive (part number DAT-USB-EXT-72=) or an optional 36/72-GB USB rack-mount DAT drive (part number DAT-USB-RM-72=), which connects through one of the four USB 2.0 ports provided by the Cisco MCS-7825-H2 server.

Identifying Server CPU Speed
As the Cisco MCS 7825-H2 matures, the processor speeds will be changed as Intel retires slower processors and replaces them with faster processors. Table 5 provides the Cisco manufacturing part number shown on the chassis to help identify the processor speed of any individual server.
Table 5. Manufacturing Part Numbers by Processor Speed
Manufacturing Part Number Located on Server
Intel Dual-Core, Pentium D, 2.8 GHz
Initial production of server
Intel Dual-Core, Pentium D, 3.4 GHz
Processor revision due to end of life of the 2.8-GHz 920 processor by Intel. This change is reflected in the product ID of the MCS-7825-H2-IPC1 changing to MCS-7825-H2-IPC2
